Which of the following processes transport oxygen from the alveoli into the capillaries?
Respiration
Inhalation
Exhalation
Diffusion
During exhalation, what will happen to these respiratory organs?

The air pressure n the thoracic cavity decreases
Air is pushed out
What is diffusion process?
Molecules move from a region of lower concentration to a region of higher concentration
Molecules move from a region of higher concentration to a region of lower concentration
